Wheel arch cover == "Wheel arch extension"

From my old Golf 2, I still remember these plastic parts that you...
'...placed on the outer edges of the fenders and, if necessary, covering the lower edge where rust or corrosion is present.'
have covered
a) Are they still around?
b) Do they happen to have the official designation 'Wheel Arch Cover'?

Best regards,
Rudi

I had listed them on the invoice as "wheel arch extensions" for my Jetta back then.

Morning!

a.) to the best of my knowledge: yes.
b.) yes

Great!
Thank you both.

Best regards,
Rudi
